Appncauon. med May es,

My invention relates' to liquid dispensers and more particularly to ,dispensing devices which are adapted to be used for supplying ink to drawing pens and the like.

It has heretofore been the common practice to supply ink to draWingpens and the like by means ofthe conventional quill se-l curedto the underside .of they usual ink bottle stopper. This` quill arrangement has certain unsatisfactory features.. One of these outstanding` unsatisfactory features resides in the fact that considerable inconvenience' is sometimes' experienced by the user vin attempting to remove the stopper from the bottle. This inconvenience is often` occasioned' as result of the drying or calting of the ink' Which has collected Within the .neck of the bottle. Thel very fact that the stopper must be removed yeach time that a pen is to be filled With a supply of ink', is in itself a decided inconvenience; Also,` it sometimeshappens, in instances Where the stopper is continuously removed at frequent' intervals, that an appreciable portion of the ink solutionpis evaporated and this results in the thickening ofthe ink remaining Within the bottle. It often happens that' the stopper is inadvertently permitted tolie on ,the desk' or drawing board for a. considerable period, thus lea-ving the inl: exposedto the" ritmos phere andsubjecting the quill and stopper to the possibility ofloss and'breakaget i y In general,y one of the primary objects of my present inventionis to'obviate` the above mentioned andy other inconveniences which have heretofore been experienced and'to this end I propose to provide a liquid container or bottle equipped with means which enablesl fr-predetermined quantity of liquid to be dispensed by merely inverting the con'- tainer.

Another andmore specific objectief my in'- vention istoprovide a dispensing device which may be very effectively employed'to supply inkV to draaving pens and the lil e, saiddevice including a'containeror bottle having means carried by a stopper Whichi Will permit a drop of inlr to be delivered into aposition-to bereceived by'a drawing hen WhenA said container orv bottle is man* ually inverted.A

"A still further object of my invention is' to providesaconveniently operable' ink dis' pensing` device ,offl economical4L and simple construction'Whiclrincludes an container or 1928. sei-iai' Ns. 281,154;

bottle having a stopper in the neck thereof, f

verted, thereby permitting a predetermined r 'quantity of inlrl to1 flow from the container through the other tube.

In addition to the above mentioned" char-` acteristics, my invention contemplates ythe provision of an ink container. having a s'topper in the neck thereof, saidY ystopper sup-v porting a pair of tubes,` one of said tubes extending Well into the container andfcapped with` a pliable sack; the` other i tube just reaching into the container and fornied at' its outer extremity so aslto fuhct'inr siniilarly to the usual quill',` the'sack carried' by one ofthetubes serving to. permit the 'introduction of a predeterminedvolume of air into the container upon inverting `the ysaine,` thereby causing a predetermined quantity or drop of inlctobe deliver-ed tothequill por? tionof the other tube in apositioii tobe re.y ceived by a drawing pen or theA like.'-

These' `and other objectsw'ill be more ap-l` parent from the following' detailed' descriptionwh'en considered in connection with the accompanying drawing,wherein:` l

Fig'l isv a vertical sectional" vieivr taken' centrally of adispensing' device embodying features of my invention; and' l Fig-.2 is a sectional v'ieiv similar to'FigL l showing the device in an invertedposition, a drawing pen indicated by; dotlpaiid `dash" lines being" shownM in association `with l 'the`4 qiill por'tionfof'y one of the tulfiestoreceive a supply of iiili' tllie'refromf p `j ,Referring'now to the drawing detailz Whrein'I have' employed likeuiuineralsfto designate similar parts throughout the'va rions figures,V it will be observed that cerf i taini features'of my'invention reside infn container or bottleff.)I lravingfa body portion t andal neck portion 6 extending4 up'ivardly therefrin A f A'stopper Sicomprised of suitable resilient material suchy as cork,`y rubber orthe like,` is; iittedvvithin theneck` v6; Saidlstopper isj provided with a suitable flanged head fl() to facilitate the insertion and remvalitherefl Fitted Within and extending through a` pair of parallel apertures formedink the" stopper 8 are a pair of tubes or condiii'tsjflQ 1 and 141 The tube yi2' isv iiu'slr at its outer ico extremity With the outer surface ot the head ot the stopper, Ithe inner extremity thereol terminating vvell Within the bottle 2 and capped With a pliable or iieXible sack 16. This sack 1G may be ot any suitable pliable material such as thin rubber material or the like. I prefer to use such material which may be readily slipped over the end oit the tube 12, the iiexibility or resiliency oli the material being suliicient to cause it to se cui-ely adhere Ato thek tube. In some instances it .might be desirable to employ a small amount ot adhesiveto secure the saclr to the tube. *When the bottle 2 occupies its normal upright position as shown in Fig. 1, the sack 16 will be submerged Within the ink 18 and the pressure` et said ink Will be sutlicient to collapse said sach.

The tube 11i is shorter than the tube 12, the lower end thereof terminating just beiorv the stopper 8, Well above the surface ot the ink-,18. The outer end 20 ot' the tube 12 is shaped similarly to the conventional quills commonly employed With steppers et ink bottles and is similarly adapted to present ink to a drawing or ruling pen 22, indicated by dot and dash lines in Fig. 2.

From the foregoing description it Will be understood that in order to lill the drawing penf22 it is only necessary tor the user to invert or tilt the bottle 2` so that it ivill occupy the position shovvn in Fig. 2. As already pointed out, the sack 16 remains col lapsed as shown lin Fig. 1, when the bottle occupies the normal upright position. lVhen said bottle is inverted and the ink attempts to flow through the tube 14., said flow is retarded by reason of the. air trapped Within the bottle above the surface of the ink. Obviously as the inl; begins to tloiv through the tube 14 from Within the bottle, upon the tilting thereof, the trapped air will become rarefied and hence the pressure externally Will be in excess ot that Within the bottle. vent the ink from reaching the quill portion 2O of the tube la unless the pressure Within the bottle is increased. It will thus be clear that I provide the sack 16 'for he purpose of permitting the introduction ot a small or predetermined amount ot air to increase the pressure above the ink suiiiciently to cause a small amount or drop 24 (Fig. 2) ot ink to flow to the quill portion ot the tube lll. the bottle Will of course be determined by the size ot' the sack which is employed and this size will be governed by `he quantity ot ink Which it is desired to have delivered to the quill. .Thus my invention provides a very simple and eiiective device tor present- 'ing 4a 4predetermined Vquantity et ink to a quill Withoutthe necessity otremoving the stopper.

vThe only place at which 'the ink 18 is eX-,

This Will positively pre- The amount ot air introduced Withinposed to the atmosphere is through the tubel 14 and the opening` Within this tube can be Vmade small enough so that the effects of subjecting the inlr to the atmosphere are negligible. In this Way the supply ott ink alivays' remains'in a splendid, Yliowable condition and the diiiiculties heretofore experienced Will be obviated. rIlie stopper 8 may very asily be removed tor the purpose of tilling the bottle and it will be clear that iii shippingv or packing the brittlel it is only necessary to have the tube r14e forced downwardly into the stopper so the quill portion 2O will clear the upper surface ot the container, thereby permitting the usual sealing cap (not shown) to be clamped in covveiing relation ivithrespeet to the stopper. It Will thus be apparent that my invention contemplates the provision ot an inl; dispensing devicewhich is not only etlective in operation but which is also oi` a very practical and economical construction.

What I claim as my invention and desire to secure by Letters Patent` et the United States is:
